No one wants to work for free; doctors have to pay for insurance and employees and their medical school loans, drug companies spend billions on each drug and 95 percent of the time the drugs will never make it to market.

And that chain of money flows to cancer patients as well. Cutting-edge pharmaceuticals are expensive and for poorer people, unless they get a cost waiver from the company, even the co-payment for insurance may be too much.

It's no surprise that when the patient's share of prescription costs becomes too high, many patients skip doses or stop taking medication entirely, according to research conducted at the University of North Carolina.

Inhibitors of both JAK and Src kinases represent promising targets for cancer therapeutics because of the central importance of these kinases in tumor cell proliferation and survival. In addition, in cancer cells activation of JAK has been reported as a compensatory effect in response to Src inhibitor exposure. This implies simultaneous inhibition of both kinases could have a synergy of anti-cancer effects compared to an agent that inhibits one or the other kinases.
 

A newly discovered system of two white dwarf stars and a superdense pulsar, all packed into a space smaller than the Earth's orbit around the sun, could allow astronomers to tackle the very nature of gravity itself.

The pulsar is 4,200 light-years from Earth and is spinning nearly 366 times per second – it was found to be in close orbit with a white dwarf star and the pair is in orbit with another, more distant white dwarf. 

The three-body system is scientists' best opportunity yet to discover a violation of a key concept in Albert Einstein's theory of General Relativity: the strong equivalence principle, which states that the effect of gravity on a body does not depend on the nature or internal structure of that body.

The cockroach in the genus Ectobius is an invasive organism and the most common cockroach inhabiting a large region from northernmost Europe to southernmost Africa. 

Astronomers has discovered the first Earth-mass planet that transits its host star and found that KOI-314c is the lightest planet to have both its mass and physical size measured.

Though it weighs the same as Earth, it is 60 percent larger in diameter, meaning that it must have a very thick, gaseous atmosphere, they note.

The team gleaned the planet's characteristics using data from NASA's Kepler spacecraft. KOI-314c orbits a dim, red dwarf star located approximately 200 light-years away. It circles its star every 23 days. The team estimates its temperature to be 220 degrees Fahrenheit, too hot for life as we know it.
